Airworthiness manages approximately 1400 approvals located not only within the UK, but also all around the world. This includes 125 overseas approvals on behalf of EASA in such locations as Singapore, Australia and China and 130 approvals on behalf of the UK Military. Airworthiness also manages 260 approvals due to the recently created Bi‐lateral agreements with the United States (FAA) and Canada (TCCA) and the soon to be completed agreement with Brazil. Beyond just approval oversight AW carries out over 1,000 SAFA inspections, 250 ACAMs, 200 CofAs &permits, Certification/design, MOR and training/consultation.

Workload Overview

Aircraft AuditPt MG

These pie charts show the percentage of time our field force (not including SAFA) within AW spend for each activity. We now have a forward looking forecast and using metric’s the ability to measure what we actually achieved. With the dynamic nature of our operational workload and the limitation of job time recording, a mismatch between actual and forecast  would be expected. Additionally the time periods for these charts also differ, but despite this, the data gives us a real insight into our workload;Oversight (Green) – The Forecast is higher than the actual, limitations of job time recording (metric’s) as a results the 5 minutes used here and there relating to oversight  tend not to get recorded correctly and get swept up into the Management Other (Bucket). Not all unscheduled tasks, which mostly consist of projects/working groups have their own metric’s code, so again they are swept up into the Management Other (Bucket).  Overall confidence in our job time recording and forecasting is fairly high, especially within the context of known limitations. All of these activities except Management and Unscheduled are directly funded via charges/contracts. Airworthiness forecasted 78% directly funded  activity and achieved 73%.

AW Findings Raised3497 findings were raised by Airworthiness in 2015. At first glance it would appear that the number of findings raised in 2013 & 2014 is almost identical. Further investigation has revealed that 2013 did not contain a complete set of data, due to the phased introduction of Q‐Pulse within Airworthiness that year. 2013 & 2014 contained general aviation data, with 2015 being the first year this data has been completely separated, which helps to explain the drop off in the number of findings raised.

Correct Root Cause identification and resolution leads to longer term improvements, with fewer repeat findings 

Process and Documentation are still recorded as the top 2 Root causes. This is possibly due to the symptom being identified rather than the Root Cause. Significantly Competence or capability, might add weight to the perception that there is an industry skills shortage

Closure Performance is a  Q‐Pulse drop down menu that records whether a finding has occurred before (repeat finding) and the quality of the organisation’s first response. This was limited to the organisation’s first response for a very good reason! If it wasn’t measured at a single point in time, then the data would be lost (as the status of the performance field got updated, eventually all findings would end up accepted).  For 2015 76% of findings responses were accepted first time, 12% rejected, 8% late and 4% late/rejected.  Rejecting an organisation’s response should be seen as evidence that the CAA is ensuring that the Root Cause has been correctly identified and fully addressed.  It also allows us to measure the effectiveness of the Organisation quality system.
